N-Heterocyclic carbene ligands bearing a naphthoquinone appendage: Synthesis and coordination chemistry

Many biochemical transformations for small molecule functionalisation depend on the temporal delivery of multiple protons and electrons. For this purpose, Nature elegantly combines transition metals with redox-active cofactors. In a biomimetic spirit, we report on the synthesis and coordination chemistry of an N-heterocyclic carbene ligand bearing a naphthoquinone moiety NHC 1. Both the silver and palladium complexes [Ag(mu-Cl)(NHC 1)]2 2 and [Pd(eta3-allyl)(NHC 1)Cl] 5 were characterized by X-ray crystallography. Cyclic voltammetry of the metal complexes suggest that redox events occur both on the naphthoquinone and on the metal for the iridium and ruthenium complexes.

Photoactivation of Cu Centers in Metal-Organic Frameworks for Selective CO2 Conversion to Ethanol

CO2 hydrogenation to ethanol is of practical importance but poses a significant challenge due to the need of forming one C-C bond while keeping one C-O bond intact. CuI centers could selectively catalyze CO2-to-ethanol conversion, but the CuI catalytic sites were unstable under reaction conditions. Here we report the use of low-intensity light to generate CuI species in the cavities of a metal-organic framework (MOF) for catalytic CO2 hydrogenation to ethanol. X-ray photoelectron and transient absorption spectroscopies indicate the generation of CuI species via single-electron transfer from photoexcited [Ru(bpy)3]2+-based ligands on the MOF to CuII centers in the cavities and from Cu0 centers to the photoexcited [Ru(bpy)3]2+-based ligands. Upon light activation, this Cu-Ru-MOF hybrid selectively hydrogenates CO2 to EtOH with an activity of 9650 mumol gCu-1 h-1 under 2 MPa of H2/CO2 = 3:1 at 150 C. Low-intensity light thus generates and stabilizes CuI species for sustained EtOH production.

Probing the excited states of Ru(II) complexes with dipyrido[2,3-a:3′,2′-c]phenazine: A transient resonance raman spectroscopy and computational study

The lifetimes and transient resonance Raman spectra for Ru(II) complexes with the dipyrido[2,3-a:3′,2′-c]-phenazine (ppb) ligand and substituted analogues have been measured. The effect of altering the Ru(II) center ({Ru(CN)4}2- versus {Ru(bpy)2}2+), of the complex, on the excited-state lifetimes and spectra has been considered. For [Ru(bpy)2L]2+ complexes the excited-state lifetimes range from 124 to 600 ns in MeCN depending on the substituents on the ppb ligand. For the [Ru(CN)4L]2- complexes the lifetimes in H2O are approximately 5 ns. The transient resonance Raman spectra for the MLCT excited states of these complexes have been measured. The data are analyzed by comparison with the resonance Raman spectra of the electrochemically reduced [(PPh3)2Cu(mu-L *-)Cu(PPh3)2]+ complexes. The vibrational spectra of the complexes have been modeled using DFT methods. For experimental ground-state vibrational spectra of the complexes the data may be compared to calculated spectra of the ligand or metal complex. It is found that the mean absolute deviation between experimental and calculated frequencies is less for the calculation on the respective metal complexes than for the ligand. For the transient resonance Raman spectra of the complexes the observed vibrational bands may be compared with those of the calculated ligand radical anion, the reduced complex [Ru(CN)4L*-] 3-, or the triplet state of the complex. In terms of a correlation with the observed transient RR spectra, calculations on the metal complex models offered no significant improvement compared to those based on the ligand radical anion alone. In all cases small structural changes are predicted on going from the ground to excited state.

Light-initiated hydroxylation of lauric acid using hybrid P450 BM3 enzymes

We have developed hybrid P450 BM3 enzymes consisting of a Ru(ii)-diimine photosensitizer covalently attached to non-native single cysteine residues of P450 BM3 heme domain mutants. These enzymes are capable, upon light activation, of selectively hydroxylating lauric acid with 40 times higher total turnover numbers compared to the peroxide shunt.

Preparation and redox studies of alpha1- and alpha2-isomers of mono-Ru-substituted dawson-type phosphotungstates with a DMSO Ligand: [alpha1/alpha2-P 2W17O61RuII(DMSO)]8-

Both alpha1- and alpha2-isomers of mono-Ru-substituted Dawson-type heteropolytungstates with a DMSO ligand, [alpha1-P2W17O61Ru II(DMSO)]8- and [alpha2-P2W 17O61RuII(DMSO)]8-, are prepared from the alpha2-isomer of a monolacunary derivative, [alpha2-P2W17O61]10-. Reaction of [alpha2-P2W17O61] 10- with Ru(DMSO)4Cl2 under hydrothermal conditions produces [alpha2-P2W17O 61RuII(DMSO)]8- as a main product together with [alpha1-P2W17O61Ru II(DMSO)]8-, [PW11O39Ru II(DMSO)]5-, and [P2W18O 62]6- as byproducts. By addition of KCl to the reaction mixture, K8[alpha2-P2W17O 61RuII(DMSO)] is isolated in a moderate yield. On the other hand, reaction of [alpha2-P2W17O 61]10- with Ru2(benzene)2Cl 4 under hydrothermal conditions produces an isomeric mixture of [P2W17O61RuIII(H2O)] 7- (alpha1-isomer/alpha2-isomer ratio: ca. 8/1) as a main product together with [PW11O39Ru III(H2O)]4- and [P2W 18O62]6- as byproducts. By addition of acetone to the reaction mixture, K7[P2W17O 61RuIII(H2O)] is isolated in a good yield. Reaction of [P2W17O61RuIII(H 2O)]7- with DMSO produces [alpha1-P 2W17O61RuIII(DMSO)]7- as a main product and [alpha2-P2W17O 61RuIII(DMSO)]7- as a minor product. By addition of KCl and acetone, the alpha1-isomer K 8[alpha1-P2W17O 61RuII(DMSO)] is isolated in a good yield. Both compounds are fully analyzed by CV, NMR (1H, 13C, 31P, and 183W), IR, UV-vis, elemental analysis, mass spectroscopy, and single-crystal structure analysis. Assuming that isomerization does not occur during the reaction of [P2W17O61Ru III(H2O)]7- with DMSO, the isolated [P 2W17O61RuIII(H2O)] 7- contains the alpha1-isomer as a main compound with the alpha2-isomer as a minor compound. Unusual transformation of the alpha2-isomer of [P2W17O 61]10- to the alpha1-isomer occurs. Redox behaviors of [alpha1-P2W17O 61RuII(DMSO)]8- and [alpha2-P 2W17O61RuII(DMSO)]8- are compared together with Ru(DMSO)-substituted alpha-Keggin-type heteropolytungstates, [alpha-XW11O39Ru(DMSO)] n- (X = Si, Ge, and P).

Ruthenium polypyridine complexes of tris-(2-pyridyl)-1,3,5-triazine – Unusual building blocks for the synthesis of photochemical molecular devices

The mononuclear compounds bis-(2,2?-bipyridine)ruthenium(ii)-(tris(2- pyridyl)triazine) [(bpy)2Ru(tpt)](PF6)21 and bis-(4,4?-di-tert-butyl-2,2?-bipyridine)ruthenium(ii) -(tris(2-pyridyl)triazine) [(tbbpy)2Ru(tpt)](PF6) 22 have been synthesised and fully characterised. The attempted syntheses of heterodinuclear complexes with the tris(2-pyridyl)triazine (tpt) ligand as bridging ligand and various palladium(ii)- and platinum(ii)-dichloro complexes using the ruthenium complexes as starting materials resulted in a partial hydrolysis of the triazine based bridging ligand in case of 2 and an unselective decomposition in case of 1. Compound 2 reacts with Pd(DMSO) 2Cl2 and Pt(DMSO)2Cl2 substituting three ligands from the metal centres of these precursors with partial hydrolysis of the triazine moiety of the bridging ligand yielding the dinuclear complexes bis-(4,4?-di-tert-butyl-2,2?-bipyridine)ruthenium(ii) -N-((picolinamido)(pyridin-2-yl)methylene)picolinamide)chloro-palladium(ii) [(tbbpy)2Ru(tptO)PdCl](PF6)23 and bis-(4,4?-di-tert-butyl-2,2?-bipyridine) ruthenium(ii)-N- ((picolinamido)(pyridin-2-yl)methylene)picolinamide)chloro-platinum(ii) [(tbbpy)2Ru(tptO)PtCl](PF6)24. The newly formed bridging ligand coordinates in a bidentate fashion at the ruthenium centre and acts as a tridentate ligand for the second metal centre. The structures of all the complexes have been fully characterised and their photophysical properties are reported. A similar reaction sequence using the (4?-(p-bromophenyl)-2, 2?:6?,2?-terpyridine)ruthenium(ii)-(tris(2-pyridyl)triazine) complex [(BrPhtpy)Ru(tpt)](PF6)25 and Pd(CH 3CN)2Cl2 as starting materials did not yield the hydrolysed bridging ligand but the expected dinuclear complex [(BrPhtpy)Ru(tpt)PdCl2](PF6)26 suggesting that the coordination of two pyridine rings of the tpt by the ruthenium centre is essential for the stabilisation of the tpt frame work. Preliminary investigations show that the dinuclear ruthenium-palladium and -platinum complexes are not active catalysts in the light-driven hydrogen production. The Royal Society of Chemistry 2009.

Arene?Ruthenium(II) Complexes with Bioactive ortho-Hydroxydibenzoylmethane Ligands: Synthesis, Structure, and Cytotoxicity

The synthesis of a series of neutral arene?ruthenium(II) complexes (arene = p-cymene, hexamethylbenzene, and benzene) [(arene)Ru(HDB)Cl] derived from the reaction of the appropriate arene?ruthenium(II) dimers and ortho-hydroxydibenzoylmethane (HDBH), a potent inhibitor of cell proliferation, is described. In addition, related ionic complexes [(arene)Ru(HDB)(PTA)](SO3CF3) (PTA = 1,3,5-triaza-7-phosphaadamantane) have been prepared. The structure of three complexes has been confirmed by X-ray crystallography. The cytotoxicity of the complexes has been evaluated against human ovarian carcinoma cells (A2780 and A2780cisR), as well as against nontumorigenic human embryonic kidney (HEK293) cells, and compared to the free ligand and cisplatin. Two of the complexes, that is from the first series with p-cymene and hexamethylbenzene, display relevant activities against the cisplatin-resistant A2780cisR cancer cell line.
